Connect the
Fiber-Optic Cable
Remove the protective caps on each connector of the cable and the PCA's ports.
Attach the cable connector with the white sleeve to the light gray transmit port
on the
HP-FL PCA
and the other connector to the darker gray receive port. This
may be easier with the
PCA
slightly extended from the
CIO
card cage. See figures
2-2 and 2-3.
Caution
At the other end of the cable, attach the white-sleeved connector to the transmit
port on the controlling drive and the sleeveless connector to the drive receive
port.
When attaching the cable to the
PCA,
be careful not to overtighten the
connectors. Use caution to avoid cross-threading the plastic port barrel. Make
the connections by hand to avoid excessive torque. Do not use tools as they may
damage the connectors.
The optical transmit port on the
PCA
must connect to the drive's receive port,
and the
PCA'S
receive port must connect to the drive's transmit port. The
standard cable is marked to make this easier (see figure 2-2).

Figure 2-2. Identifying the Transmit and Receive Cable Connectors
If you connect the transmit ports to each other and the receive ports to each
other, no damage will result, but the link will not work. (See the "Verify Link
Operation" section later in this chapter. The red S and R LEDs will light. )
Cables from a Non-HP
Duplex fiber cables from other manufacturers will have a different scheme to
Source
help you identify a single fiber at each end of the cable. For example, one fiber
may have a stripe along its length, while the other fiber does not. Connect the
fiber with the stripe to the transmit port (light gray) and the unstriped connector
to the receive port (dark gray) on the
HP-FL PCA.
At the disk drive end of the
cable, connect the striped fiber to the disk drive's receive port and the unstriped
fiber to the disk drive's transmit port.
